    摘要： By using two probe optical systems for measurement by disposing the probe optical systems with a test object sandwiched therebetween, an optical path length of light transmitted through the test object which is identified locally is calculated using an interference signal thereof. In addition, a geometrical thickness of the same part is calculated by measuring positions of the probe optical systems, whereby two calculated values are obtained. Based on the values and a calculated value for a reference object, a refractive index distribution of the test object is obtained.

    摘要： An inspection method for evaluating the performance of an optical component at high precision is provided. According to the inspection method, a first light beam 24 and a second light beam 26 both having different phases are generated from light which has passed through an optical component 18, and are interfered with each other to form an interference region 30. A linear line 66, a linear line 70 and linear lines 72 are set within the interference region 30 so as to determine a distribution of light intensities on each of the linear lines 72. Then, a frequency corresponding to the maximal light intensity is determined. Further, an approximated liner line or an approximated curved line is determined from a plurality of frequencies determined for each of the linear line 72. Then, the aberration of the optical component is evaluated based on the coefficient of the approximated linear or curved line.

    摘要： A lens evaluation method includes diffracting light derived from a lens so that two diffracted rays of different orders (e.g., a 0th-order diffracted ray and a +1st-order diffracted ray) interfere with each other, thereby obtaining a shearing interference figure, and changing phases of the diffracted rays. The method also includes in the shearing interference figure, determining phases of light intensity changes at a plurality of measuring points on a measuring line which passes through a midpoint of a line segment interconnecting optical axes of the two diffracted rays, and determining characteristics (defocus amount, coma, astigmatism, spherical aberration and a higher-order aberration) of the lens based on the phases.
